AIIVIPROVIEIIl/iCEllil'I IN COMBINED OYSTERLKNIFE AND ICE-PICK The Schedule referred to in these Letters Patent and making part ef the same.

I, WILLIAM PATTBERGER, of the city of Philadelphia, and State of Pennsylvania, have invented certain Improvements in Clam and Oyster-Knives and I ce- Pickerl combined, of which the bllowin'g is 'a specification.

The nature of my invention consists in a combined .oyster-knife and ice-pick, and is constructed withv a rod or wire, which connects at one end with the shank of the blade by means of a hook at one end, the said shank and rod being passed through a central bore oi' the handle, and a hook on they other end of the rod being pressed into a cross-groove in the end of the handle,l to hold the shank rmly in place.

The rod being so placed, is held securely against a side of the central bore above mentioned, by means of' a stopple, which I make ot gum or cork, to keep out the water and prevent the parts rusting and the wire is of such length as to drawfthe shoulder of the shank firmly against the contiguous end of the handie, to exclude the water at that end.

rIhe blade is kept 'from turning in the handle, by means of a pin which projects from one side of the shank, and tits in a cross-groove inl the end of the handle. This groove is like the groove in the other end of the handle, mentioned above, to provide for reversing the ends ol' the latter, as hereinafter described. v

The invention further consists in the combination of. an ice-picker with the handle, which is kept in the central bore above mentioned, when not in use, and arranged in proper position for use when wanted, as

i hereafter described. i

To enable others skilled in the art to which my improvement appertains, to make and use my invention, I will now give a full description thereof.

In the accompanying drawings, which make a part of this specication- Figure 1 is an isometrical view of the improved clam and oyster-knife, which, in its outward appeal'- ance, is similar to the ordinary implement.

Figure 2 is a longitudinal section of the same.

Figure 3 is a perspective view of the rod C) 'Figure 4 is a like view of the picker I).

Figure 5 is alongitndinal section with the ice-picker D, in connection with the handle B.

Like letters in ail the figures indicate the same parts.

A is the blade, and

B is the handle or stock.

The handle is constructed with a central bore, a, in which the shank b of the blade A is placed, at either the small or large end of the handle, as may be desired, and is securely held by means ofthe rod or wire C,'one end of which has a hook, c, which is placed in a hole in one side of the shank b,- at the point 1. The

other end basa like hook, c, which engages with the the shank b, and enters a cross-groove in the end of the handle at the point 3, to prevent the shank turning,l so as to keep the blade A inits normal position.

The arrangement of the several parts thus described, is seen in figs. 2 and 5.

The groove at the point 3 is made like the one at the point l, s0 that-:the knife or blade A may be con- .nected with either end of the handle B, to suit the business.

It will readily be seen that the constructionof the blade and handle in separate pieces, as above described,

admits of an indefinite number of blades being usedY i in4 succession with a single. handle, so that as one wears out it may be replaced withA a new one, Vor a different kind of knife may take the place of one in connection with the handle, at any time, to snit the work 'to be done.

Another advantage will be seen inthe fact that the blades can be tempered more evenly and better, separately, than when made in connection with the han? dle, in the usual manner, and are not so liable to vbe burned in tempering; but the fact that `a new blade may take the place o' a'worn'-out or broken one, at "a verylittle cost, is a great desideratum.

I combine, with the handle B, an ice-picker, D, as

seen in fig. 5,the but end of the picker coming against the shoulder f of the connecting-rod C.

` The rod is represented in detail in. iig. l3, and the n picker in iig. 4. v f

When the picker is not in use, it is placed'in` the bore a of the handle B, as represented in iig. 2.V

There is a cork or gum stopple, E which closes the outer end of the bore a, and eectually. prevents "the i ingress of water. It also, by bearing against the side of the rod C, keeps the latter against the contignous side of the bore b, and thus prevents the hook c' being disconnected with the groove in the end of the handle B.

When the knife has to be replaced, or the ends of Athe handle reversed, the stopple E is removed, and

the ice-picker D dropped out of the bore b. Then, by pushing the\hook c out of its connection with the groove in the end of the handle B, a light tap on the end of the rod C will disengage the blade from Athe handle. y

The rod C may then he connected, in like manner, spring C, held in place by the cork or stopple E, and with the same or :mother knife, as above described, ioe-picker D, arranged substantially as described. A:1nd the knife connected with the handle in like man-, In testimony that the aboveis my invention, I have nel', ns above mentioned. hereunto set my hand and afxed my seal, this 19th Instead of the shank b being connectedto the handziy of October, 1869.

die B, as described, it may be screwed into the bore a. WILLIAM PTTBERGR. [14. s.]
